This sand and water table is a great alternative to a traditional sandbox. The table stands a couple feet tall, so kids do not have to climb inside to play with it. It has two sides, one for sand and one for water. Each side has a removeable plug, so that water can be drained out.
The umbrella that comes with it is useful, since we don't have a lot of shade in the yard. It comes with a top that bungees on. The top seems fairly durable, but is made of pretty thin plastic. It makes it lightweight so the kids can remove it, but I can see where it might become easily torn thus exposing sharp edges. The body of the table is a single piece of plastic, and is very durable.
Inevidably it will all become one big "mud" table, but the kids have fun with it just the same. It comes with plastic molds, but we bought a few beach toys to go along with it.
